GENERAL DESCRIPTION The ADuM120x are dual-channel digital isolators based on
Analog Devices’ iCoupler® technology. Combining high speed
CMOS and monolithic transformer technology, these isolation
components provide outstanding performance characteristics
superior to alternatives such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with
optocouplers. The typical optocoupler concerns regarding
uncertain current transfer ratios, nonlinear transfer functions,
and temperature and lifetime effects are eliminated with the
simple iCoupler digital interfaces and stable performance
characteristics. The need for external drivers and other discrete
components is eliminated with these iCoupler products.
Furthermore, iCoupler devices consume one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM120x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). Both parts operate with the supply
voltage on either side ranging from 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. In
addition, the ADuM120x provide low pulse-width distortion
(< 3 ns for CR grade) and tight channel-to-channel matching
(< 3 ns for CR grade). Unlike other optocoupler alternatives, the
ADuM120x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and during power-up/power-down conditions.

SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION All voltages are relative to their respective ground. 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V. All min/max specifications apply over the
entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5 V.
Table 1.
The supply current values for both channels are combined when running at identical data rates. Output supply current values are specified with no output load
present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section. See
Figure 6 through for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See through Figure 11
for total I

DD1 and IDD2 supply currents as a function of data rate for ADuM1200 and ADuM1201 channel configurations. The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.
3 The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed. tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal. tPSK is the magnitude of the worst-case difference in tPHL and/or tPLH that is measured between units at the same operating temperature, supply voltages, and output
load within the recommended operating conditions. Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier. CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate. See through for
information on per-channel supply current for unloaded and loaded conditions. See the section for guidance on calculating per-channel supply
current for a given data rate.
